PHENIX Run-15 Status
Douglas Fields PHENIX Run-15 Run Coordinator
University of New Mexico
Time Meeting 2/3/2015Douglas Fields 2
Status of Preparations
• PHENIX is (mostly) ready for Run 15 start of physics.
• We are under full shifts.• MPC-EX North and South integration ongoing. • FVTX/VTX are in good shape.

• All fibers have sync, but NW5 because of a broken transceiver (top figure).
• Only 1 / 768 columns does not latch (top figure).
• No bias problems at this moment.• Overall 95% hit efficiency
according to the last calibration (bottom figure).
• Have ~7 wedges which do not properly receive a calibration signal but still perform fine for real data taking.

1) - Inspected cables connections, LV, HV, optical cables. Issued were found and fixed 2) Low Voltage (LV) turned ON: all (40) ladders responded properly to low voltage (all working). 3) Bias voltage turned ON (10 volts, to check the connections): all (40) ladders responded properly with nominal currents.

MPC-EX• Both North & South are setup for PHENIX• All Layers are being read out by DCMs
– Still in standalone mode while firmware is being tested– Entire readout chain tested
• GTM->FEM->Detector->FEM->DCM
• Working on multi-event buffering: critical to high-rate, low dead time PHENIX DAQ– Some issues, but a lot of progress over the past few weeks
Fake data from the Carrier Board- Tests the connection to the FEM
Time Meeting 2/3/2015
Detector performance• Temperature & leakage current monitoring– Leakage current increases with temperature
• Cosmic MIP studies are ongoing at SBU– Calibration possibilities
Time Meeting 2/3/2015Douglas Fields 9
Summary
• We are quickly coming to a ready state.• Still plan to be ready to take physics data
and commission MPCEX on Feb. 9.
